Abstract: This study deals with the theoretical description of heat transport and flow distribution in a helium heated steam reformer with segmental baffles. For this purpose a two dimensional, transient computer code is developed, which is described in detail. A first application of this code is demonstrated by designing an 8.25 MW steam reformer for the planned AVR-process heat plant. In a parameter study the sensitivity of such a heat exchanger to the variation of some constructional features is demonstrated and the above mentioned 8.25 MW steam reformer is optimized by the aid of the so gained knowledge. Finally the transient behaviour of the hot gas duct and the steam reformer of the AVR-process heat plant during start up is investigated. It is shown, that, from the technical point of view, it will be possible to start operating the process heat loop with a helium temperature above 600 °C while keeping within safety requirements.
